Several years ago most of fans complained because we didnt have players like Costa or Cuadrado. Now Costa is useless and we should get rid of him. He can be frustrating when he tries too much but when it pays off, it pays off in dividends. Someone like Costa can change the game, he can create a chance and beat his marker. He can be a menace on his day. The lack of playing time is because he is seen as replacement for Dybala. In current setup they cant coexist. The problem is neither of Ronaldo, Dybala and Costa can track back, hence there is Mandzukic to provide balance.
